Postural Control is an ability to maintain the body ‘s Centre of Gravity (COG) within the limits of stability as determined by base of support. The was differences of motor control of activities of daily living such as walking and lifting of a healthy individuals compared to LBP patients. It was proven that LBP patients may have impaired control over trunk posture and movement. Dynamic control is important in many functional tasks as it required integration of appropriate levels of proprioception, range of motion, and strength [1].

  Patients with Chronic Low Back Pain (CLBP) presents with paraspinals and other trunk muscle weakness and reduce in coordination of lower back muscle. Thus, this reduction in muscular strength and coordination affects postural stability, balance and neuromuscular control in patients with CLBP.‘ Leinonen reports that delayed response of trunk muscles could be related to inaccurate information processing from higher centers of the central nervous system related to motor control. Individuals with low back pain have longer reflex latencies compared to healthy people as there are delayed response of stimulus of the muscle and reflex during sudden load response. These longer latencies is a pre-existing risk factor that could affect the balance of trunk of CLBP patients. Additionally, the absence of visual feedback, poorer balance performance has been associated with longer onset times of the trunk muscles. There was increased displacement of the centre of pressure while standing upright and greater medial – lateral postural sway for individuals with CLBP as they present with balance deficits [2].
